Study Concerning the Influence of Acrylic Consolidating Agents
on Gold Gilding and Schlagmetal

Abstract:

The first intervention realized in the case of art works with a precarious state of conservation is the consolidation of support and superficial layer. Generally for the puzzle-like painting layer the preventive consolidation is an urgent intervention, which will be followed, after a succession of interventions, by a definitive one. Furthermore, if the polychrome layer is pulverous, the binder will be applied over the entire degraded surface. In both of cases, the binder can damage the polychromy and gildings. For this purpose, this paper studies the influence of acrylic binders upon gildings with gold leaf and schlagmetal, respectively the manner in which these binders are applied and the effects they have upon them. For the experiments there were used samples of fir tree gilded with gold or schlagmetal or other imitative products that are on the market. After gilding the samples were coated with acrylic binders and put in the oven, for artificial ageing. The analysis were realized with optical microscope, SEM-EDX and spectrophotometer in CIE L*a*b*system. Keywords: gilding, schlagmetal, acrylic adhesive Binder, artificial aging, SEM-EDX, CIE L*a*b* colorimetry
